I can relate.
A few years ago I was in San Francisco and saw the cutest French kid ever with his host parents I think. First, I saw him as we were walking down the street. Then a few hours later I saw him at a Japanese restaurant. Then, the next day, I saw him at a museum. (It was very weird seeing the same guy 2 days in a row, especially in a big city like San Fran.)
I was so upset when I didn't see him anymore. I should have talked to him, but I was young and shy and he didn't seem to speak English too well.
But now I look back and it didn't really matter too much.
